the coal into the car or other receptacle to be filled.

The trestle-work F,instead of being placed in close proximity to thetrack, may be placed on a Wharf, and the chute may direct the coal intovessels to be loaded, or the chute may be so constructed as to directthe coal into a second conveyer or chute and carry it to a distantpoint, if necessary.

I have given a brief description of one of the machines for carrying outmy vprocess in order to clearly set forth the process; but itwill beunderstood that other forms or styles of machines may be used from myinvention.

In Fig. 6 I have shown a conical pile of coal piled by the mechanism setforth in my application, Serial No. 806,980, .and have shown merely .theconveyer B, pivoted .at a fixed point c, dispensing entirely with theconveyer A.

It will be understood that inpiling the coal the'piles will varyaccording ,to the locality The conveyer attacks the pileof coal, asshown in Fig. 1, along its base, 'anddisturbs the integrity of the.pile-in fact, eats into thel pile throughout .the entire extent ofcontact of the conveyer, 4and not at a single .'point, as in the case ofshoveling by hand Aorrby an excavatwithout departing ing-machine. Thecoal, as soon as disturbed bythe action of the conveyer, flows bygravity into the conveyer-trough and is carried along by the iiights ofthe conveyer to the point of delivery. It will thus be' seen that thecoal is handled gently and flows onto the conveyer by gravity when theangle of repose is broken, and when once on the conveyer the coal iscarried to the point of delivery without any breaking or disintegrationof the same, as would be the case in carrying out the processes usuallyemployed prior to my invention, the direction of removal being laterallypast and away from the pile, and the conveyer being advanced toward theconstantly, receding point of supply until the entire pile has beendisposed of. f v

I claim as my invention- The mode herein described of effecting the.removal or distribution of storage-piles of coal or like gravitatinggranularl material, which consists in continuously attacking the pilealong one side of its base, thus causing the material to flow by gravityon that side Aof the pile which is attacked, catching said tmy
